There is no single treatment that can cure lichen planus completely. However, treatments are available to help manage the symptoms and make living with it easier. For example, steroid creams or ointments are often used to help relieve the itch and control the rash. Most cases of lichen planus of the skin clear up on their own within 6 to 9 months. The rash rarely lasts longer than 18 months. However, oral lichen planus and lichen planus that affect the genital area may be more persistent.
